Abstract

Much recent empirical evidence shows that \textit{community structure} is ubiquitous in the real-world networks. In this Letter, we propose a growth model to create scale-free networks with the tunable strength (noted by QQ) of community structure and investigate the influence of community strength upon the collective synchronization induced by SIRS epidemiological process. Global and local synchronizability of the system is studied by means of an order parameter and the relevant finite-size scaling analysis is provided. The numerical results show that, a phase transition occurs at Qc0.835Q_c\simeq0.835 from global synchronization to desynchronization and the local synchronization is weakened in a range of intermediately large QQ. Moreover, we study the impact of mean degree <k><k> upon synchronization on scale-free networks.
